The HP Data Environment • Data from the Great Observatory reside in a distributed environment and are served from multiple sources. • Multimission Data Centers • Solar Data Analysis Center • Space Physics Data Facility [CDAWeb, OMNIWeb, etc.] • The Community Coordinated Modeling Center • Mission-level active archives: e.g. ACE, TIMED, TRACE, Cluster, etc. • Much of our data are served from the individual instrument sites. • We are moving into a new data environment of • Virtual Observatories for convenient search and access of the distributed data, and • Resident Archives to retain the distributed data sources even after mission termination. • We have a Data and Computing Working Group to help us move ahead.
Vision for the Heliophysics Data Environment • “Report and Recommendations of the LWS Data System Planning Team”, Winter, 2002. • The Heliophysics (nee SEC, Sun-Solar System Connection) Data Environment: • Will be based on existing services and evolve in response to user needs -> no new data system • Will allow for the selective inclusion of essential data sets and modeling from other sources. • Requires science participation in data management -> no new data system management group • The environment will be distributed and virtual. • Will have peer-reviewed process for elements of the environment.
Corollaries to the Vision • Heliophysics data environment needs to support all heliophysics research activities and programs. • The “Right Amount of Glue” sets the philosophy. • J.B. Gurman (Fall 2002 AGU, SH52C-03) • Technology is or will be ready • XML plus software tools become the new standard (the ‘glue’) • A standard of behavior - share one’s data with everyone • The Virtual Solar Observatory is a path-finder. • Activate/Energize discipline-based approaches to the evolution of the data environment. • The SPASE dictionary will be the ‘Rosetta Stone’ for HP data models. • Distributed funding and implementation activities. • Blend ‘bottoms-up’ implementation approaches with ‘top-down’ vision for the whole scope of an integrated data environment.
Agenda • Welcome (McGuire & Roberts) • Introduction (Holmes & Bredekamp) • The Invocation (Gurman) • Status and plans reports from funded VxO Activities (~10-15 min) • VSO, VSPO, GAIA, VSTO • VHO, VITMO, VIRBO, VMO/G, VMO/U • Science constituency served • Who’s Doing What (People and Institutions) • Datasets to be made available • Services • Overall architecture including Technology, Data Model, etc. • Milestones/Timeline • Methodology for user feedback
Agenda (cont’d) • A conversation about SPASE and the VxOs and other Data Centers (Roberts, Thieman, T. King) • What is SPASE and its Data Model? • Status of the Data Model and tools for its use • Proposed plan for populating registries and for model feedback • Open discussion of suggestions and plans • Value-added services for VxOs (10-15 min each) • SPDF, COSEC, tbd • Future directions • Ideas for coordination and collaborations • Approaches for evolving to THE VHPO • Ideas/models for transitioning capabilities developed to operating infrastructure • Next steps in gathering user requirements, priorities, concerns for data and services • Building community buy-in and enthusiasm to data environment efforts • Community Workshop Planning • Next VxO technical workshop • Ideas and volunteers for organization, timing, topics etc
Charge to the Workshop • What we are trying to accomplish: • Promote the VxOs to collaborate [sharing info and how to], • Start the dialog for integrating upwards in order to break down the barriers between the sub-disciplines, and • As we proliferate the VxOs: assist the data services - don’t confuse them. • Our researchers don't know the barriers; why should we impose artificial ones?
The Virtual Solar Observatory • Completed prototype development • Organized by the solar data services • SDAC • NSO • Stanford • Montana State Univ • Small box approach but ‘extensible’ • See the Design Proposal and other info at http://virtualsolar.org
2002 Concept for the Heliophysics Data Environmentvia ‘small boxes’ • Virtual Solar Observatory • Virtual Heliospheric Observatory • Virtual Magnetospheric Observatories • Virtual ITM Observatories Services <-> VxOs <-> Analysts’ tools
Think ‘small box’ • Limit the initial set of data services • Place additional or future data services on the ‘to do’ list • Limit functionality and capability • Focus on the core functions of data query and retrieval • Share (publish) the schemata • Schemata are referenced via registered URLs • VxOs work w/ data services to create and maintain schemata • Analysts work w/ the VxOs to create, debug and update the query engines and APIs • Each VxO needs an associated software library of data manipulation and analysis tools • E.g. SolarSoft library serves the solar research community
